Modes Of Operations: Blanket Control - Gaymar Medi-Therm III Manual Del Operador

Modes of Operation/BLANKET CONTROL
6.0 Modes of Operation
The Medi-Therm III machine is designed to operate in
three (3) modes:
• BLANKET CONTROL (water temperature control),
• PATIENT CONTROL (automatic patient temperature
control), and
• MONITOR ONLY (patient temperature monitoring).
When the Medi-Therm III machine is turned on, the set
point defaults to 37°C for both the BLANKET CONTROL
mode and the PATIENT CONTROL mode. If either set
point is changed, the new value is retained in memory
until power is removed.
6.1 BLANKET CONTROL
When operating in BLANKET CONTROL mode, the
Medi-Therm III machine regulates the water temperature
to the selected SET POINT. A temperature sensor within
the machine monitors water temperature, and the
machine heats or cools the water as required to bring it
to the SET POINT temperature.
In BLANKET CONTROL mode, the operator must observe
the patient's temperature and manually adjust the water
temperature to obtain the desired results.
To operate in BLANKET CONTROL mode:
1. Perform all start-up procedures (pp. 6-7).
2. Press the BLANKET CONTROL button. The upper
window on the top of the BLANKET CONTROL
button will light.
The BLANKET display will indicate water
temperature. The SET POINT display will indicate
the default temperature (37°C ) at start-up, until
selecting the SET POINT temperature in step 3
below.
Adjust the SET POINT display to the prescribed
3.
water temperature setting (4°C to 41°C). See
page 5, SET POINT CHANGE.
The STATUS display will indicate WARMING or
COOLING while the machine is heating or cooling
the water. When the water temperature stabilizes
(within 1.0°C of the SET POINT temperature), both
the WARMING and COOLING lights will turn off
indicating that the desired water temperature is
being maintained.

NOTE: It takes approximately 8 minutes or less to
raise the water temperature from 22°C
(room temperature) to 37°C.
NOTE: Within the SET POINT range of 30°C
to 41°C, if the water temperature does not get
to within 1.0°C. of the SET POINT temperature
after 4 hours, the WATER display will flash and the
audible alarm will sound. Additionally, if the WATER
temperature reaches the set point and then deviates
by more than 1.0°C for more than 10 minutes, the
WATER display will flash and the audible alarm will
sound. When this occurs:
• Pressing the ALARM SILENCE button will
silence the alarm for 10 minutes.
• Check the patient's condition and consult
with a physician.
• Changing the set point will restart the four-
hour timer.
4. Check the integrity of the skin
according to department protocol when
regulating temperature with external
devices. Frequency of assessment and
documentation will vary depending upon
the individual response of the patient.
Failure to monitor patient may result
in skin damage or inappropriate
patient temperature.
5. While operating in the BLANKET CONTROL mode,
the patient probe may be used to monitor the
patient's temperature.
To observe patient temperature, insert sensing end
of patient probe into patient and tape securely to
prevent accidental dislodgment. Insert plug end of
patient probe into PATIENT PROBE jack. Make sure
probe plug is fully seated.
Use only Gaymar probes or equivalent
YSI 400 series probes approved for use with
medical devices. If in doubt that the correct probe
is being used and is operating properly, perform a
PROBE CHECK test (p. 13).
Patient temperature will be indicated on the PATIENT
temperature display.
